Control shrinkage, wall thickness, gates, and ejection during design and production.
Material selection
Choose the PE grade that fits the part
Selecting the right polyethylene grade is central to product performance. Our engineering team matches material behavior, melt flow index, shrinkage, and end-use requirements to the molding process.
| Feature | HDPE High-Density PE |
LDPE Low-Density PE |
|---|---|---|
| Properties | High strength-to-density ratio; rigid | Highly flexible, ductile, and impact resistant |
| Chemical resistance | Excellent | Excellent |
| Typical products | Industrial parts, containers, heavy-duty housings | Flexible seals, caps, and squeezable packaging |
| Processing | Careful cooling helps control shrinkage | Flows easily through complex, thin-walled molds |
| Surface finish | Smooth, matte, or textured | Soft-touch or semi-gloss |
Production capabilities
From product concept to production-ready parts
We bridge engineering and manufacturing with a coordinated process designed for cost efficiency, dimensional stability, and dependable delivery.
Discuss your projectCustom mold design
Tooling is designed around PE shrinkage characteristics and critical mating surfaces to support practical tolerances.
Precision injection
Our 50–1,000 ton molding machines support parts from 1 g precision components to large-scale industrial housings.
Secondary operations
Assembly, ultrasonic welding, and custom packaging help deliver ready-to-use PE components.
Quality control
Production runs are inspected for gate vestige, flash, wall thickness consistency, and dimensional stability.
Applications
PE parts for packaging and demanding environments
Chemical inertness, flexibility, impact resistance, and moisture resistance make PE suitable for a broad range of commercial and industrial products.
Packaging industry
Durable caps, closures, and containers requiring chemical resistance and food-grade compliance.
Industrial equipment
Corrosion-resistant components, seals, protective guards, and heavy-duty housings.
Consumer products
Flexible household items and components that need reliable impact resistance and comfortable handling.
Medical and laboratory
Disposable components and fluid-handling parts supported by PE’s non-reactive properties.
Engineering support
Design for manufacturing starts early
PE is a semi-crystalline material with thermal behavior that must be considered during design. Our engineers provide DFM feedback before tooling to reduce risk and improve part consistency.
